. proveinents n lvl eans Fropelling Boats, of which the rollowing is a specification.

The invention relates to removable, mechanical means of propulsion for small boats and the like, and the principal features of my improvements may be soon: arized as follows: l. Propeller shafts, ca rying propellers, and adapted to be removably connected to the gumvale of a boat, as at both sides thereof. 2. Means enabling the propeller shafts to be adjusted in length. 3. Hand operated mechanical. means for rot-sting the propellers. 4. ltleans for steering the boat by manipulating the propellers alternately at either side of the boat.

In the drawingsaccompanying this application, Figure 1 is a side elevation of a boat ."tted with my improvement. Fig. 2 is a front view thereof. Fig, 3 is an enlarged elevation of the propeller, with its operating shalt, mechanism, and means of connecting to the side of a boat. i is a section on the line 44 of Fig. 3. Fig. 5 is a partial, sectional view of the propeller shaft and tub Fig. 6 is a side view of the complete apparatus. Fig. 7 is an enlarged, sectional detail of the propeller driving mechanism, and Fig. 8 is a detail of a clamp.

Brie'lly my invention. consists of a pair of propellers, attached to the ends of propeller sha'lts that are removably attached, one at each side of boat, and depend therefrom into the water, a crank or each propeller shaft being provided Within the boat Whereby the occupant of said boat may cause said propellers to be rotated to propel and steer the boat. To this end I provide a clamp, as

A, adapted to be reinovably attached to the gumvale a 01' a boat, as by a screw 61,. The

clamp has the alined be rings a for a crank shaft (1 which carries bevel gear a}, and has a crank a. The screw a impinges against a clamp plate B, ivliich lies against the outer surface of the gunwale, with a lip 7) extending beneath its under surface. Screws 7) I), passed through threaded lugs at the upper portion oi plate B, and Which'bear upon clainu A, assist in securing clamp A against vcrti displacement. Clamp A hasapend est plate A, havin means oi; attachment to Specification of Letters Patent.

QF BROOKLYN, NEW

Patented June 19 3? A hollow bloc-l: E, renlovably secured in the upper end of the-tube C, as by screws s is provided with rollers 0 forming a bearing for the upper end of propeller shart F. This propeller shaft F has a groove 7' which re .ceivesa spline 9' carried by telescoping tube G that forms a part of the propeller shaft, and isadapted to extend its length. Thus, as Will be observed, the length of both the propeller shaltancl its tubular casing may be adjusted to suit the conditions ail'ecting the use of my improvement. The lower portion of tube D is 1 roviderl with roller bearings d for tube G, W ichlatter carries the bevel gear H. 'lube'li 'also carries an extension frame or brackjet D ,'having the journal boa-ring d for sh aft'l Tlvhich latter carries propeller. J at one end, and bevel gear 'i at its other end, in mesh with the bevel H. A brace rod K, extendin from the lower end of tube C: to the gunwa e of. the boat, is there secured by a clamp L (see Fig. 8) and serves to maintain the set position of the propeller tubes against the leverage exerted through the action of the propeller.

The crank c extends into the boat in posi tion for its handle to be conveniently turned by a person sit-ting on a transverse seat, in the manner of a rower. As tivo of these propelling devices are employed, one at each side of the boat, a crank handle is provided for each handot the operator, who can, by turninghis cranks separately, and by rovers-- ing them control the operation of the boat in any direction, besides being able to propel it at a good rate of speed.

It will be observed that the tube C having the extensible tube D is, when attached to parts, exerts a moving influence to the boat- I in a horizontal plane. It will lurtl'ier be noted that by this arrangement the dev may be connected to the boat by clamp at desired position longitudinally of the 1 gunwsle of the boat. Thus if it is desired to operate several pairs of propelling devices,

the may be placed at (llil erent points along l l cured in "place, and shifted and readjusted in the simplest and most expeditious manner gjossmle, as is obvious clamp A, whereby the apparatus may be se l l l l A further .11;-
